Answer:
inequality is n< with the line under 12 or n= , with the line under it 12
Step-by-step explanation:
Answer:
Direction parabola opens upward.
Vertex of parabola is (27,-9).
Axis of symmetry is
.
Step-by-step explanation:
Note: Option sets are not correct.
The vertex form of a parabola is
...(1)
where, (h,k) is vertex and x=h is the axis of symmetry.
If a<0, then parabola opens downward and if a>0, then parabola opens upward.
The given function is
...(2)
On comparing (1) and (2), we get
, so direction parabola opens upward.
, so vertex of parabola is (27,-9).
So, axis of symmetry is
.
I believe the answer is D.
Answer:
840mi. - 12 hrs
x - 3 hrs
This is a simple cross multiplying problem.
840 _ 12
x -- 3 ⇒12x=3(840) ⇒ 4x=280 ⇒ x=70 miles
:D
